Brief Answer:
no, but examination is required by surgeon

Detailed Answer:
Hi and welcome.
This is probably seroma or hematoma and it would be good if this is drained out by needle or incision before it become infected. This is not something life-threathening but surgical therapy is definitely required especially if there was already a revision. If this is abscess with pain redness and fever then he should visit ER. Wish you god health. Regards
